Members of the Peterborough County OPP and emergency crews were called to an ATV collision on Peninsula Road near Kasshabog Lake, shortly after 10:00pm on Friday.
The male rider of the ATV allegedly lost control and struck a tree. Police say the injures were made worse due to the lack of safety equipment used by the rider.
The 27-year old male rider from Havelock, Ontario was transported to a Toronto area hospital with serious injuries. Police continue to investigate the cause of the crash.
